The specific embodiment
With reference to accompanying drawing 1, it has partly shown according to connecting bridge of the present invention, and the connecting bridge in the present invention is a kind of retractable boarding bridge that comprises roller.It comprises bridge body passageway and awning device 1, and this awning device 1 comprises door-shaped frame 2 and docking framework 3, and docking framework 3 is directly used in realizes docking of awning device 1 and airframe shell.Docking framework 3 comprises stereoplasm frame 4 and the flexible frame 5 that will directly contact with fuselage cover, and flexible frame 5 is made by flexible material, but the ductility of this material is relatively poor, for example plastics.The flexible frame surrounding also can comprise padded coaming, inflatable packer or elastic variable pipe etc. further.Door-shaped frame 2 is fixedly connected on floor layer 6.Described floor layer is the non-telescoping formula flaggy regularly that can't change shape.4 of stereoplasm frames are articulated in the floor layer 6 of awning device 1 pivotally, and use energy storage equipment between door-shaped frame 2 and stereoplasm frame 6 and reclaim winding mechanism 8, and energy storage equipment can be for example gas spring 7.Flexible frame can be articulated in the front end on floor, but as a kind of selection, also can be fixedly installed on the floor.In order to be added to open area, preferably, stereoplasm frame 4 and flexible frame also can be arranged on the lateral surface of floor layer.On each side, be connected with a plurality of actuators between stereoplasm frame 4 and flexible frame 5 (in order to adapt to various fuselage surface curvature, can accept in scope at cost, the quantity of actuator is preferably The more the better), for example hydraulic actuator 9, consider for simplifying, in the present embodiment, the number of hydraulic actuator is three, and on even keel is arranged between stereoplasm frame 4 and flexible frame 5 respectively.These three actuators are preferably on each side that is distributed in dispersedly flexible frame, but the top of the rarest each side branch that is arranged on flexible frame preferably in a plurality of actuator is beneficial to the applying of flexible frame and fuselage cover.Actuator one end and flexible frame 5 carry out hinged, and the other end is hinged with stereoplasm frame 4.Also be respectively arranged with distance measuring sensor 10 in two side ends of floor layer front end (floor and flexible frame hinge-point below) and flexible frame 5 both sides branches, this apomecometer can be for example ultrasonic range finder, infrared ambulator or laser rangefinder, the preferential laser rangefinder of selecting in the present embodiment.The installation of apomecometer on flexible frame can be adopted well-known conventional means, for example can adopt the form of support to be arranged on flexible frame, and this laser rangefinder also can be arranged among perforate on flexible frame 5, and apomecometer can the deflection along with flexible frame flexural deformation.Apomecometer quantity on flexible frame can be identical from actuator quantity also can be different.The set laser rangefinder of floor layer front end can be arranged in the boring of floor layer front end.Under initial condition, distance measuring sensor 10 in the vertical directions that arrange on floor layer front end and flexible frame 5 should be alignments, that is to say that they should be arranged on same vertical straight line.Certainly, for the purpose of protection apomecometer, their edges should slightly retreat in the edge of flexible frame or floor layer front end, can not cause shock to apomecometer like this when docking.Apomecometer in each branch of flexible frame is crisscross arranged with respect to actuator, specifically, apomecometer should be tried one's best and is arranged at dispersedly on flexible frame, but should avoid being in the hinge-point of very close actuator on flexible frame, this use for apomecometer is very favourable, therefore described hinge-point often suffers stress, this is unsafe for apomecometer, consider it is also favourable from installing space in addition, simultaneously due to they installation of staggering, thus also less for the infringement of flexible frame.The peripheral surrounding in the space between stereoplasm frame, flexible frame and door-shaped frame is equipped with awning.Awning device 1 also comprises the controller (not shown) that is arranged on door-shaped frame 3 rear upper lateral parts, be used for to receive the signal that laser rangefinder obtains and the operation of controlling hydraulic actuator 9 and winding mechanism 8, goes back in addition controller and also controls a warning device.Therefore this controller can have following function: cause that when boarding due to the passenger connecting bridge trembles with respect to airplane skin, and then give the alarm when causing the connecting bridge docking larger distance of framework detachment machine body shell (being for example 10 centimetres) and warn the passenger to postpone action, and again start wind2 release energy storage equipment or primer fluid hydraulic actuator, until measuring distance, laser rangefinder reenters safe range (sounding all clear).
The below at length introduces the method for operating of the awning device 1 in the present invention.
at first, at awning device with before fuselage cover contacts, use the initial stage at connecting bridge, the laser rangefinder of opening on awning device is measured flexible frame apart from the distance of airframe, vertically advance towards retractable aircraft at connecting bridge and (can utilize two apomecometers that are arranged at the floor layer leading section, if the distance of their two measurements equates, illustrate that connecting bridge just vertically advances towards aircraft), and when approaching the aircraft certain distance that will dock, this distance is (because aircraft surfaces is arc line shaped, therefore the data of each laser rangefinder measurement are different, distance herein can be any data that measure in laser rangefinder) in the time of can being the arbitrary set point value between 0.5-5 rice, preferred 1 meter, temporarily stop connecting bridge near the motion of aircraft, the distance value that controller measures according to each laser rangefinder is controlled each actuator and is carried out separately flexible with the distortion flexible frame.Concrete operation method is as follows:
With reference to accompanying drawing 2, it has schematically simulated the mode of texturing of the flexible frame of the awning device in the present invention.At first utilize the measured distance apart from fuselage of apomecometer on flexible frame and floor layer, generate the surperficial radian of the fuselage cover that will dock via the controller simulation, as shown in mark 101; Because the flexible frame in the present invention is articulated in the fixed type floor, therefore flexible frame bottom position after distortion remains unchanged, therefore according to the above-mentioned radian that calculates, flexible frame after the distortion divides and prevaricates as shown in mark 102 (translation radian 101, and vertically highly can draw in conjunction with flexible frame) as can be known; Because the stereoplasm frame 106 of simulation keeps motionless, and the hinge-point position of actuator on flexible frame fix, and the vertical extension of flexible frame can ignore, and therefore relevant elongation or the retracted length of the actuator after distortion just can calculate.And then controller according to aforementioned calculated amount activate flexible frame after hydraulic actuator of the present invention can be realized being out of shape can have with will in conjunction with the identical radian of fuselage cover.Mark 103,104 in this figure, 105 is the flexible frame in representative simulations, the actuator after flexible and the actuator of initial position respectively.In addition, in order more accurately to guarantee the distortion of flexible frame, the present invention can also arrange the auxiliary actuator (not shown) between actuator and stereoplasm frame, because the simulation deflection angle of actuator 104 in the frame deformation process can calculate according to the method described above, therefore can come actuator between deflection flexible frame and stereoplasm frame according to the angle of calculating with auxiliary actuator.Described computation process can be completed by controller, and relevant mathematic calculation is all the common practise in affiliated field.
In this process, the framework both sides are independent operation respectively, the distortion that is to say flexible frame both sides can be different when needed, and this is very favorable when larger corner occurring for the hatch door periphery, so the present invention has very outstanding alerting ability in docking operation.Therefore and the actuator in the present invention just completed actuating before docking, can or not occur transshipping because of the control system error due to the fault of self.
After this, namely continuing to control connecting bridge advances, and (the laser rangefinder measuring distance of stronghold front edge of board and the comparison of anticipated value when moving closer to airframe, described anticipated value and apomecometer are relevant with respect to the installation site at flexible frame edge) the connecting bridge speed of advance that slows down, until flexible frame when fitting in fuselage cover (the laser rangefinder measuring distance of stronghold front edge of board and the comparison of anticipated value) brake connecting bridge.
Then controller is controlled winding mechanism release energy storage equipment, make it will dock framework and closely be pressed on fuselage cover, due to the flexible frame in the present invention by actuator-operated distortion, therefore the energy storage equipment in the present invention need not to apply like that larger thrust in prior art, has therefore also just reduced the risk that awning device damages fuselage cover.
In the passenger boards process, because the extruding of external conditions or passenger's weight causes awning device with respect to fuselage cover generation deflection or disengaging, can measure the variation of distance due to laser rangefinder, if therefore the distance of flexible frame and fuselage cover reaches a predetermined threshold (being for example 10 centimetres), controller can be controlled accordingly warning device and give the alarm, and again start wind2 and discharge energy storage equipment or primer fluid hydraulic actuator, reenter safe range until laser rangefinder can measure distance, sound all clear.
Just had the surperficial radian of fuselage cover due to the engage frame in the present invention before the applying fuselage cover, therefore can improve sealing property, reduced simultaneously the hurtful risk of fuselage skin.Also have advantages of in addition alarm and again revise the applying degree.What below do not elaborate is all the common practise in affiliated field.
Those skilled in the art can make replacement or modification to content of the present invention according to content disclosed by the invention and the art technology of grasping; but these replacements or modification should not be considered as breaking away from the present invention's design, and these replacements or modification are all in the claimed interest field of the present invention.
